Answer to Question #42103 in Molecular Biology for Erin

Question

A particular poison works by interfering with the enzyme required to synthesize tRNA. AT which step in protein synthesis will the process be stopped?

A) Elongation
B)Termination
C) Initiation
D)Replication

Answer 1

Elongation, termination and initiation are steps of protein synthesis. Replication is the process of DNA doubling, in other words, nucleic acid synthesis.
Initiation and elongation of protein synthesis requires participation of tRNA. That is why, the process can be stopped at this stages. If the poison is added before the synthesis starts, the process will stop at the stage of initiation.
Thus, the correct answer is C
